GAGE.

SPECIFICATION forming part of Letters Patent No. 456,331, dated July 21, 189.1. Application iiled February@ 1891. Serial No. 380|837. (No model.)

To all whom it may concern.-

Beit known that I, GEORGE A. HINDEs, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Gages, of which the following is a specification.

My invention relates, specifically, to that class of gages used in gagin lgdoor-j am bs, doors, and the like preparatory to putting hinges thereupon; and it consists of certain new and useful features of construction and combinations oi' parts hereinafter described, and pointedout in the claims.

Referring to the accompanying drawings, which form a part of this specification, Figure l is a perspective View of my improved gage in the operation of cutting a vertical groove in the face of a door-jamb preparatory to forming a mortise therein to receive one of the leaves of a hinge. Figs. 2 and 3 are respectively top and under side views of the gage. Fig. 4 is a section of the same at the dotted line A 1L in Fig. 3. end view of the door-jamb, having its face and edge gaged, ready to out a hinge-leaf mortise therein.

Like letters of reference indicate corresponding parts throughout the several views.

A is the gage-block considered as a whole, provided with longitudinal and transverse recesses A A2 in the under side thereof to receive the gage-bars B B', which are longitudinally adjustable by being slid therein. The gage-block is also provided with guides A3 A4, which traverse the edge and face of a jamb when the same is being gaged for mortising.

A5 AG are longitudinal and transverse slots iextending through the gage-block into the recesses A A2 therein.

The gage-bar B is provided with a cuttingwheel B2, mounted in its outer end, the outer face of said wheel being flat and parallel with the face of the guide A3, its periphery having a sharp edge and its inner face being beveled therefrom toward its axis. The gage-bar B is constructed in the same manner as the bar B and equipped with a cutting-wheel B3, identical wit-h the cutting-wheel B2. The gage-bars B B are also provided with thumb-screws B4 B5, inserted .through the slots Ai AGA in the gage-block, for securing' the same in position when longitudinally adjusted.

Fig. 5 is an O is a door-ja-mh.

O is an inside casing-of a door (not shown) opening inward.

Fig. lshows the manner of using the gage toy makethe cut C2 ou theface of the jamb O.

The cut C3 in the edge of the jamb O is made by applying in like manner the guide A4 of the gage to the face of the jamb O and propelling the same the requisite distance.

The cutting-wheels B2 Bii of myrgage make sharply-defined clean cuts, leavingthe edges C4 C5 of the unfinished mortise full and completely finished to receive the outeredge and inner portion of the inside face'of the hingeleaf. Moreover, these cutting-Wheels are not deflected out of their course by the grain of the wood forming the jamb to be cut, nor by means of gu mmy or hard spots or small knots therein.

The gages now in common use are defective in the respect-s just noted.

The gage-bars B B', when not in use, may be slid completely into their respective re- As a new and compact article ot' manufacture this gage' surpasses any now in use.

l. In combination, the gage-block having the longitudinal and transverse recesses therein, the gage-bars adapted tobe longitudinally adjusted iu said recesses and provided with cutting-wheels mounted iu their outer ends, the outer faces of said cutting-Wheels being iiat,tl1eirperipheries having sharp edges and their inner faces being beveled therefrom toward theiraxes, and the thumb-screws for securing said gage-bars in position when adjusted, substantially as and for the purpose specified.

, 2. Asa new compact article of'manufacture, the gage-block A, having the longitudinal and transverse recesses A A2 therein and being provided with guides A3 A, the longitudii'ially-adjustable gage-bars B B', having cutting-wheels B2 mounted in their outer ends, and the thumb-screws for securing said gagebars in position when adjusted, substantially as and for the purpose specified.
